Moving the dredge

The dredge floated in about nine feet of water- but it could move anywhere it wanted in the valley because it took its pond with it.

Hard to imagine, isn't it? It worked because the dredge dug a pond for itself to float in as it moved — scooping material in front and filling in behind.

The whole process took place in water and using water. At the front, the buckets brought gravel and rock into the dredge, and water poured into the hole that was left behind.

The material went through the dredge and was processed using water. At the end of the process, the tailings — rock and gravel with no gold in it — went onto the 96-foot chute of the stacker, and were deposited behind the dredge in piles.

The operator up in the control area set the cables to determine how deep the bucket line would go. He pulled them back to engage the bucket line, and began the dredging process.

When the dredge had finished scooping away a swath of bank, the operator used the cables to drag the dredge forward again, and the process started all over.
